Kudos to “Techno Claus,” played recently by David Pogue of The New York Times on CBS “Sunday Morning,” for adding the Roku L7 Streaming Player ($49.99 at roku.com) to his gifts list this year. This is the box TV junkies need to stream Netflix, Amazon Instant Video, Hulu Plus, HBO GO and more on a television that’s not hooked up to a mulit-functional electronics device like a Blu-ray Player. Roku simply shows online content, and that content has exploded in recent years. Meanwhile, Roku prices keep falling. This is a great gift for the person who’s ready to ditch cable or satellite TV, with their perplexing bills and moving-target rates, or who just wants to expand their TV-watching options.
